Q: 2. What are all the field names posted to the callback page, and can I add custom fields?

If you reuse your web integration of Curlec Checkout inside a web view on Android or iOS, the checkout form may not open. Issues like this are handled in our

Android SDK

and

iOS SDK

, with the SDKs being the preferred method of integration.

However, if you want to reuse the web integration for some reason, you can pass the following callback_url along with other

checkout options

to process the desired payment:

callback_url needs to accept incoming POST requests. For a successful payment, the callback URL will have razorpay_payment_id, razorpay_order_id and razorpay_signature as the request parameters.

For failed payments, the request parameter are explained in the table below:

error

object The error object.

code

string Type of the error.

description

field

string Name of the parameter in the API request that caused the error.

Handy Tips

You can set query parameters with callback_url, to map it with entities at your side. For example, following is a valid callback URL:

https://your-site.com/callback?cart_id=12345
